Serial No.553,877.

In the production of a commode or bedpan well adaptable to use with aninvalids bed of the general type shown by U. S. patents to Fazalerley:1,208,721 of November 7, 1916; 1,257,072 of February 19, 1918 and1,545,415 of July 7, 1925, diliiculty has been encountered in providinga light, convenient, easily manufactured, and otherwise'practicalstructure which will possess an easily cleanable interior of no largersize than needed, and will at the same time possess the relatively largesubstantially rectangular exterior needed for snug reception between theseparated liead, foot and hip-supporting mattress sect-ions of the bed.Diculty has also been encountered in producing a pan upon which` thepatient may comfortably lie.

It has been'the primary object of my invention to overcome the abovedifliculties and in so doing, 1 have devised the novelconstruction'hereinafter described and claimed and shown in the accompanyingdrawings, and while said construction is designed primarily for use inbeds having separable mattress sections and pan elevators, it could inmore shallow form, be well adapted to handpositioning in the customarymanner upon a conventional mattress.

Fig. 1 of the accompanying drawings is a top plan view of a bedpanconstructed in accordance with my invention. l

VFig. 2 is a vertical longitudinal sectional view on line 2-2 ofyFig.r1.

Fig. 8 is a perspective view of the seat- `upper edge is suitablysecured to the plate 8,

so that the three parts 8, 9, and 10 form aunitary structure.

The top plate 8 which forms a seat upon which the patient lies 'or sits(when reclining) is of substantially rectangular form and is providedwith an opening 11, the portions 12 of said plate along opposite sidesof said opening and the portions 18 within the rear corners of theplate, being concave. The front end of plate 18 is provided with anintegral upwardly projecting horn 14 which is open at its rear and atits lower end and communicates with the opening 11. At opposite sides ofthe horn 14, the plate 8 is provided with longitudinally convex portions15V to support the users thighs immediately below the hips. The rearportion of plate 8 is formed with a central longitudinally extendingchannel 16 which opens upwardly, forwardly and rearwardly, said channelbeing of suiiicient depth and width to accommodate the bones at thelower end of the spinal column so that said plate will not exertpressure upon the flesh in this region and cause discomfort. Theformations 12, 18 and 15 conform substantially in shape to the portionsof the body with which they contact and hence the patient may be muchmore comfortable upon the improved pan and the channel 16 preventspainful pressure, than ordinarily.

The bottom 17 of the inner pan 9, is flat at its front portion buttoward its rear, is curved both longitudinally and transversely andinclined slowly toward the rear end of the top plate 8, as seen at 18,being integrally joined to said top plate. The side wall 19 of the pan 9merges at its rear into the inclined bottom portion 18, but in advanceof the latter is inclined inwardly, being integrally joined at its upperedge to the plate 8, between the opening 11 and the peripheral edge ofsaid plate.

The outer pan 10 is of substantially rectangular form and is providedwith a side wall 20 whose upper edge is solderedor otherwise secured tothe plate 8 along the peripheral edge of the latter, said edge of saidplate 8 being preferably provided with a shouldered liange 21 to whichsaid upper edge of the wall 2O is secured. Along the'lines of juncturebetween the wall 2O and the plate 8 and between the inner pan 9 and saidplate 8, fluid-tightness exists, so that no fluid may enter the spacebetween the two pans.

The lower portion of the side wall 19 of the inner pan 9 )referably liesagainst the side wall 2() to sti en the latter against beingaccidentally bowed or dented inwardly, and the bottom 17 of said innerpan 9 lies upon the front portion of the bottom 22 of the outer pan 10.The rear portion Q3 of the pan bot-- tom 22, is upwardly arched underthe inclined portion 18 of the inner pan 9, the arched formation Q3extending from side to side of the pan and hence providing a downwardlyopen recess 24 to accommodate a nurses or other attendants fingers tofacilitate handling of the pan, particularly when Sliding the latterfrom an elevator 25 which zis used for raising or lowering it when theimproved pan 1s employed upon a bed of the type above mentioned. Thelower corners of the pan 10, at its front and rear, are provided withribs 26 in the present disclo- 23sure to slidably engage gulde channels27 on the elevator 25.

Not only does the novel construction herein disclosed, provide acomfortable pan, but it also provides one which may be easily man-3(yfufactured, easily cleaned and conveniently handled. The inner pan 9is free from any abrupt corners and is shaped to best permit emptying,the horn 14 being of course used as a discharge spout, as well as meansfor ss'guiding urine into the pan. The entire structure, both internallyand externally, may be quickly, easily and thoroughly cleaned, so thatthe device may be kept in a constant state of sanitation.

Preferably, the inner pan 9 and the top plate 8 are formed from a singlecasting of light metal or alloy, but the outer pan may be formed easilyfrom suitable gauge sheet metal, and obviously the entire structure4S3may be covered with baked enamel or the like,

for appearance as well as cleanliness.

The longitudinally convex portions above described, are transverselyconcave in the preferred construction. This formation uhas a tendency tokeep the thighs close to the horn or hood 14 so that there is no dangerof urine splashing from the pan in use.

I claim 1. A bedpan comprising a seat-forming top plate having anopening, an inner pan and an outer pan under said top plate, the innerpan being free from abrupt corners to facilitate cleaning, the two pansbeing fluidtightly joined along their upper edges to *o said top plateand forming therewith a unitary article.

2. A bedpan comprising a seat-forming top plate having an opening, aninner pan and an outer pan under said top plate, the

' inner pan being free from abrupt corners to facilitate cleaning, oneof said pans being integrally joined luid-tiglitly along its upper edgeto said top plate, the other pan being formed separately from said topplate but fluid-tightly joined along its upper edge thereto.

3. A bedpan comprising a substantially rectangular seat-forming topplate having an opening, an inner pan whose upper edge is integrallyjoined fluid-tightly to said top plate between said opening an theperipheral edge of said top plate, the rear portion of the pan bottombeing slowly inclined rea-rwardly and all portions of said pan beingfree from abrupt corners; and an outer substantially rectangular panfluid-tightly joined along its upper edge to said top plate along theouter edge of the latter.

6. A bedpan comprising a substantially rectangular seat-forming topplate having an opening, an inner pan Whose upper edge is integrallyjoined fluid-tightly to said top plate between said opening and theouter edge of the plate, and an outer substantially rectangular panwhose upper edge is joined {luid-tightly to said top plate along saidouter edge of the latter, the bottom of said inner pan lying at itsfront portion upon the bottom of said outer pan but at its rear portioninclining slowly toward said top plate, the side wall of said inner panmerging into said inclined rear bottom portion, the portions of saidinner pan side wall in advance of said inclined bottom portion beinginwardly inclined and at their lower portions lying against the sidewall of saidouter pan.

7. A bedpan having a. seat plate provided with an opening, and a centrallongitudinally extending channel in the rear portion of said seat plate,said channel opening upwardly through said seat plate, opening forwardlyinto said opening, opening rearwardly through the rear end of said seatplate, and being of sufficient depth and width to prevent pressure ofthe seat plate upon the lower part of the users spinal column.

8. A bedpan having a concave seat plate provided with an opening andhaving at its front end an upwardly projecting centrally disposed,rearwardly and downwardly open horn; said seat plate having legsupporting faces at opposite sides of said horn, said faces being convexlongitudinally of the pan, the rear part of said seat plate beingprovided with a central, longitudinal, channel which opens upwardly,opens forwardly into said opening and opens rearwardly through the rearedge of said seat plate, said channel being of sufficient depth andwidth to prevent pressure of the seat plate upon the lower part of theusers spinal column.
